Foaming and conditioning detergent composition

Abstract

This invention relates to a foaming and conditioning composition, especially a liquid detergent conditioning composition having a low viscosity and able to provide in the bath tub a desirable quantity of suds and water-insoluble oil material having skin-softening or emollient properties.

What we claim is: 
     
       1. A foaming and conditioning composition providing suds and a layer of emollient oil upon addition to water consisting essentially of a mutually, insoluble mixture of a water-soluble foaming organic detergent and a water-insoluble oily material having skin-softening or emollient properties, neither the detergent nor the oily material being soluble in the other in an amount greater than about 0.1% by weight of the solvent material, the composition being substantially anhydrous, the viscosity of the composition being less than 500 centipoises, and the organic detergent being present at a level of from about 10% to about 60% by weight of the composition, being in the form of finely divided particles containing at least 50% by weight of an organic surfactant selected from the group consisting of anionic, nonionic, cationic, zwitterionic and amphoteric surfactants, and having a moisture content of less than 5% by weight, at least 90% of said particles being of a size to pass a 100 mesh screen and at least 50% of said particles being of a size to pass a 200 mesh screen, and said particles having a bulk density of at least 0.4. 
     
     
       2. The composition of claim 1 wherein the detergent particles contain at least 75% by weight of organic surfactant. 
     
     
       3. The composition of claim 1 wherein the detergent particles contain at least 90% by weight of organic surfactant. 
     
     
       4. A composition according to claim 2 wherein at least 70% of the particles pass through a 200 mesh screen. 
     
     
       5. A composition according to claim 4 wherein the moisture content of the detergent particles is less that 2%. 
     
     
       6. A composition according to claim 5 wherein the moisture content of the detergent particles is less than 1%. 
     
     
       7. A composition according to claim 2 wherein the detergent particles are prepared by freeze-grinding. 
     
     
       8. A composition according to claim 2 wherein the organic surfactant is selected from the group consisting of anionic, nonionic, amphoteric and zwitterionic surfactants. 
     
     
       9. A composition according to claim 8 wherein the water-soluble foaming organic detergent constitutes from 20% to 50% by weight of the composition. 
     
     
       10. A composition according to claim 8 wherein the organic surfactant is selected from the group consisting of alkali metal alkyl glyceryl ether sulfonates wherein the alkyl has from 10 to 18 carbon atoms; amine oxides having a long-chain alkyl radical of from 8 to 24 carbon atoms; alkali metal olefin sulfonates of from 8 to 24 carbon atoms; and mixtures thereof. 
     
     
       11. A composition according to claim 10 wherein the water-soluble foaming organic detergent includes a surface-active material selected from the group consisting of fatty acid monoalkanolamides, fatty acid dialkanolamides and mixtures of fatty acid monoalkanolamides and fatty acid dialkanolamides. 
     
     
       12. A composition according to claim 11 wherein the water-soluble foaming organic detergent includes a mixture of lauric monoethanolamide and lauric diethanolamide in a weight ratio lying between 10 to 1 and 1 to 1. 
     
     
       13. A composition according to claim 2 wherein the oily material having skin-softening or emollient properties is a mineral oil. 
     
     
       14. A composition according to claim 13 wherein the organic surfactant is an alkali metal alkyl glyceryl ether sulfonate wherein the alkyl group has from 10 to 18 carbon atoms.
